METAL DOOR.

Application filed October 5, 1922. Serial No. 592,484.

To all whom t may concern.'

Be it known that I, EDWARD J. ZAr-INER, a citizen oi the United States,residing at Laporte, in the county of Laporte and State ot Indiana, haveinvented certain new and useful Improvements in Metal Doors, oi' whichthe following is a specification.

The invention relates to metal doors, and has for its object to providea door of this character wherein the opposite sides of the door areformed from single sheets ot metal stamped in such a manner as to formthe opposite sides of the panel, the opposite sides ot the rails and theopposite sides ot the stiles.

A further object is to provide the panel adjacent the rails and stileswith inwardly struck tongues, which tongues form recesses for thereception ot tongues carried by moldings in such a manner that the outertacings of the molding tongues are flush with the Also to construct thedoor in such a manner that it may be easily and quickly assembled andthe parts spot welded, thereby obviating the use of rivets, bolts andthe like.

vWith the above and other objects in view the invention resid-es in thecombination and arrangement of parts as hereinafter set forth, shown inthe drawings, described and claimed, it being understood that changes inthe precise embodiment ot the invention may be made within the scope ofwhat is claimed without departing` from the spirit of the invention.

In the drawing Figure 1 is a front elevation of the door.

Figure 2 is a ivertical transverse sectional view through the door,taken on line 2 2 of Figure l.

Figure 3 is a perspective view of a sheet or metal for forming one sideof the door, showing the sheet before being bent to torm.

Figure 4 is a perspective view of one side of the door showing the saineafter being formed. y

Figure 5' is a detail sectional view taken on line 5-5 of Figure 4.

Figure 6 is a detail perspective view of one corner of the door.

Figure 7 is a detail perspective view ot a portion ot the molding,showing one ot' the securing tongues carried thereby.

Figure 8 is a detail perspective sectional view through a portion of oneot the sides of the door, showing a portion ot' the 1nolding securedthereto.

Referring to the drawings, the numeral 1 designates a door, which doorcomprises a panel 2, stilles 3 and rails 4. The door is formed fromsheet metal and the opposite sides thereolI 'from single sheets otmaterial similarly shaped, as shown in Figures 3 and 4. The sides 5 ofthe door are formed trom single sheets ot metal 6, which sheets areprovided with extensions 4, which when the .sheets are bent at 7 tooffset the portions 4 form the opposite sides of the rails 4 of thedoor, and longitudinally disposed portions 3a, which when bent at 8,form the opposite sides ot the stiles 3, said sides being ottset fromthe body ot the sheet 6. The sheet 6 is provided with interstices 9,which when the sheet is bent at 7 and 8 allow the ends ot the railforming portions 4a, and the inner sides of the stile forming portions3a to come into abutting engagement as clearly shown in Figure 4.Portions 4a eX- tend beyond the ends ot the portions 3a, therefore itwill be seen that when the portions 4a are bent at their outer ends 4b,will be in alignment with the ends of the stile forming portions 3,shown in Figure 4. Secured to the inner sides ot the stile and railforming portions, after the sides ot the door are formed, are plates 10,which plates are preferably secured by means oit spot welding the platesat 11 tol the portions 3a and 4, thereby rigidly forming the side of thedoor in suoli a manner that the abut ting edges will be in a closeengagement so that after the door is painted, grained or enameled thejoint will be invisible. During the stamping operation, the outer s ideset the stile forming portions 3a are bent downwardly at 3b, therebyforming lianges 12, which `flanges when the door sections 5 are placedin registration with each other extend inwardly and engage each other at13, at which time a securing strip 14 is spot welded at 15 to the flange12 tor securing the sides 5 ot the door together. The upper and lowerends ot the door so formed have disposed between the rail formingportions 4a and the stile forming portion 8a a channel member 16, theflanges 17 ot' which eX- tend outwardly and are spot welded at 18 to therail 'forming portions 42L and the stile forming portions 3a. It will beseen that the body of the sheet 6 will form the panel 2 of the door andthat the door is provided with an angle shoulder 18, preferably at aright angle to the panel 2 for the reception of a molding 19.

During the Stamping operation the sheet 6 forming the opposite sides 5of the door are provided with elongated recesses 20 which are formed bystriking inwardly tongues 21, which tongues are struck inwardly to a po*sition where their outer faces are in the same plane as the inner faceof the sheet 6. The recesses 2() receive tongues 22, which are similarlyShaped and are carried by the molding 19 on the inner side thereof. Thetongues 22 extend under the flange 23 of the molding 19 and upwardly inengagement with the inner side of the iiange 23 and is spot welded at 2Ato the flange 23. It will be seenrthat when the molding 19 is applied tothe opposite side of the door, that the tongues 22 will be received inthe recesses 20. The tongues 22 are of substantially the Same thicknessas the depth of the recesses 2O and of substantially the same size,therefore it will be seen that their outer faces will be flush with theouter faces of the panel 2 and that they may be easily and quickly spotwelded at 25 tothe tongues 21. After the tongues 22 have been secured tothe tongues 21, the door is finished in the usual manner, that ispainted as a whole, grained or ena1n eled. By so connecting the moldingit is obvious that the molding may be quickly attached and that byforming the tongues 22 of the same depth and size as the recesses 2Othat after the door is painted or enameled the sides of the recesseswill be invisible.

If so desired the molding 19 may be attached to the sides 5 forming thedoor before said sides are assembled.

From the above it will be seen that a metallic door is provided whereinthe opposite sides thereof are formed from single sheets of metal, andthe molding attached thereto in such a manner that the cost ofmanufacture is reduced to a minimum and that the dooi` may be quicklyassembled, thereby reducing the cost of labor to a minimum.

The invention having' been set forth what is claimed as new and usefulis 1. A metallic door comprising a panel, stiles and rails, the oppositesides of said door being formed from single sheets of metal, each sheetcomprising substantially right angularly disposed offset portionsforming the sides of the stiles and rails, said offset portions beingformed by a bending operation as distinguished from a-drawing orstamping operation. n

2. A metallic door comprising a panel, Stiles and rails, said doorhaving itsI opposite sides formed from single sheets of material havingsubstantially right angularly form as distinguished from a stamping anddrawing operation.

3. The combination with a metallic door comprising a panel, stiles andrails, said door being formed in two sections and from sheet metal, eachsection being provided with offset portions forming the opposite sidesof the Stiles and rails, of a molding for said door formed independentof the door, said molding extending around the edge of the paneladjacent the stiles and rails, struck in members carried by the oppositesides of the panel and forming recesses, tongues carried by the innerside of the molding and adapted to be received in the recesses andextending beyond the inner edge of the molding.

1. The combination with a metallic door having a panel and offset railsand stiles forming shoulders around the panel, of a molding engaging theshoulders and the panel, tongues carried by the inner side of themolding and disposed within recesses of the panel and having their outerfaces flush with the outer face of the panel.

5. The combination with a metallic door panel carried by offset portionsforming rails and Stiles, said rails and Stiles forming shoulders aroundthe panel, of means for securing a molding around the panel inengagement with the shoulders, said means comprising tongues carried bythe inner side of the molding and disposed within recesses of the panel,said tongues being secured to the bottoms of said recesses and ofsubstantially the same width as the recesses and having their outerfaces flush with the outer face of the panel.

6. The combination with a metallic door panel and a molding, of meansfor securing Y EDVARD J. ZAHNER.
